    Ok guys, 3 plates of steel on top in 3 2 1.....
    Meanwhile they is in a bunker, and the line i just wrote down starts at 13:44.
    But at 13:48 we see people standing right there, no protection what so ever.
    Not that far away.
    So why are they in this bunker?

      Some of the footage is taken out of the context for presentation and doesn't equate or time with the real surrounding.
      English is not my first language. But Have you seen any awards show, the reaction of the celebrities to the performers is not accurate or real. It's edited, sometimes out of context for the purposes of narration. They may be crying for a dead hog but if the editors want then they can attach the clippings timed to another moment.

      ​@@Diogenesthedog0 Thats not the case here though. At 14:14 you can see one of the bombtecs just standing out there for just a frame before the explosion. Also at 14:00 you can see that same person running to shelter when they realized its gonna rain steel plates. The Mythbusters Crew probably has to be in the bunker for insurance reasons. Rightly so as the footage shows...

    If the seal is good enough, i think you can lift an entire ship with a single vacuum cleaner. Once the vacuum is done you dont need any more suction

    Jugoslavia was not part of the Soviet bloc, it was independent. It got to communism in it's own way with no real influence from the Soviet-Union which let to a frosty relationship pretty much forever. Yugoslavia is one of the few countries that liberated itself from the Nazi's so wasn't part of either bloc. It's also why the Yugo was relatively well known as it was exported to the west which didn't happen with Soviet products.

      @@wilfredoUbatuba Not really afraid. It was just that the Soviet-Union was seriously overstretched and Stalin didn't have the resources to spare.
      He had all his focus on Germany. Yugoslavia also was hostile to the west and wasn't in the way so for Stalin it was best to mostly just leave them be.
      The resources of the Soviet-Union were better spend defending their position in Germany and also rebuilding after the war.
      Greece was actually in a similar position with it kicking out the Germans themselves and having a massive communist movement. However the British invaded to protect the king and destroyed the communists. Stalin made no move to help them cause again he didn't consider it worthwhile.
      With the Korean war Stalin gave his approval but didn't really allocate many resources to it.
      Stalin was a very cold hearted pragmatic man. If it didn't serve his interests he didn't care if communists got slaughtered.

      @@MrMarinus18 Correct me if I'm wrong but what I meant is that Stalin tried to kill Tito several times but failed miserably. And Tito sent a letter to Stalin telling him it would not take that many attempts to succeed. Hence the fear, because it seems Staline didn't try his luck with Tito anymore

      However he didn't have the resources to spare to take it by force.
      I don't think it's an opinion to state that the Soviet-Union was a much stronger nation than Yugoslavia.

    haven't finished the video yet but on the first explosion they should have placed something like a bag of water on top of the explosive, it's actually used with some explosives to direct the shockwave and focus the energy of the explosion like a shape charge and avoid wasting pretty much half of the explosive force that goes upwards, water works great because its not compressible and even though the explosion displaces it it doesn't do it fast enough like the air in front of a plane when it goes past the speed of sound and generates a sonic boom
    edit: ok, they did it with metal plates the second time but still water works better

    As for the vacuum lifting stuff...
    Check out Matthias Wandel. (if i spelled that correctly)
    He is a great guy making great videos, one of which shows you how to make a device that can lift out your patio tiles easily. NO heavy lifting or anything like that.
    A simple construction, a vacuum cleaner of some sort, and voila, he lifts out patio tiles weighing i dunno how many kilo's.
    And so yeah, duh.
    They lift heavy glass windows all the way up skyscrapers using a few suction cups.

    • @bertjesklotepino
      @bertjesklotepino Месяц назад

      but i do have this question about it: i see that Jamie and Adam keep their vacuum running while lifting.
      And so does Matthias if i am not mistaken.
      Is it not possible to install a valve in the hose to just cut off the flow and maintain the vacuum?

      ​@@bertjesklotepinovacuum cleaners are not better at moving air than their motor. They are also not one-way when not running.
      So, when the motor stops, the air that was pulled out will return through the motor, as air moves naturally from areas of higher pressure to areas of lower pressure.
      If the motor was specifically made to seal air from returning, then it may be possible.
      Just look at how some youtubers make vacuum chambers, and the devices they use to do so.
      Take this with a grain of salt, though, I'm sleepy and may be misremembering.

      That it is impossible to lift a patio tile with a vacuum cleaner?
      Because if you think it is, i urge you to check the channel of Matthias Wandel and you can see it for yourself how he made a simple wooden construction and some other stuff, put it together, and he is on video lifting his patio tiles with ease. Heavy tiles.
      Thick concrete tiles.

    Convection current pulling in dust at the bottom. That's amazing. And giant chunks of steel flying out of the debris cloud.
    Yup, i do remember having seen that before, some 23 years ago.
    Funny part is: Now it is 11 11.
    NEIN not involved.
    Anyway....
    In those days the material seen blown outwards was called Dust Puffs.
    And even if you thought it was some kinda explosive doing that.... certain people had excuses like: Nah man, that is air pressure which causes that.
    Imagine going along with such a nonsense story just because you got some money.

    Why would they use a front-engined car for the vacuum lift??? If they'd used a mid-engined car, preferably with 50-50 weight distribution, they would have achieved a much better result with the octopus design. The suction was clearly there, but the balance was all wrong.

    Oh Dear, I don't know why I watch this pseudoscientific twaddle because it is so irritating.
    They never, of course, reply to criticism - why should they when peddling nonsense to the masses and making a lot of money.
    Let's look at this episode.
    Car Lifting - of course you can lift a car with vacuum. 1 ton rolls of newsprint are moved daily with vacuum grippers. The maths are simple and obvious.
    However - my BS detector was operating.
    1. A vacuum cleaner needs air going through it to cool the motor. No air flow = motor heating and either burnout or an over-temperature cut-out turning off the motor.
    2. The plywood boxes would not stand the air pressure they were exposed to and would collapse.
    Now the car squashing.
    The principal of an explosively driven flying plate is well known, but not apparently to these clowns.
    It requires very precise initiation of the driving charge to produce a plane wave. There was no description of how the ANFO was initiated and, in any event, it is a very poor explosive for this purpose.
    The end result suggests that the whole lot was initiated in the centre whilst it should have been initiated at the periphery.
